Name | Unsaturated resin |
Synonyms | Unsaturated Polyester Resin |
Unsaturated resin is a thermosetting resin that contains unsaturated bonds and can form a hardened material through chemical cross-linking reactions. The types of unsaturated resins include liquid unsaturated polyester resin, unsaturated polyester resin, unsaturated polyamide resin, etc. They have a wide range of applications in industrial production and manufacturing, such as shipbuilding, wind and solar energy industries, building materials, automotive components, and other fields.
Nature:
1. Chemical stability: Unsaturated resins have good chemical stability at room temperature and are not easily susceptible to chemical corrosion.
2. Good flowability: Unsaturated resins have lower viscosity and good flowability, which is beneficial for coating and filling operations.
3. High strength: After curing reaction, unsaturated resin has high strength and stiffness, suitable for applications that require high strength.
4. Corrosion resistance: Unsaturated resins have good corrosion resistance and are suitable for use in humid or corrosive environments.
Usage:
1. Manufacturing composite materials: used to manufacture high-strength and lightweight structural materials such as fiberglass and carbon fiber composites.
2. Coatings: Used in fields such as exterior wall coatings and furniture coatings, it has good weather resistance and wear resistance.
3. Adhesive: used for bonding and bonding various materials, with good adhesion and durability.
4. Sealant: used for building sealing, pipeline sealing, and other occasions, with good sealing and corrosion resistance.
Method:
The preparation methods of unsaturated resins mainly include polymerization, heating curing, and UV curing. Generally, unsaturated monomers are mixed with crosslinking agents, catalysts, etc., and then reacted and cured to form solid resins.
Security information:
1. Maintain good ventilation: Avoid the harm of unsaturated resin vapor to human health.
2. Avoid contact with skin: Liquid unsaturated resins may have irritating effects on the skin, and gloves should be worn to avoid contact.
3. Eye protection: Avoid unsaturated resin splashing into the eyes, causing eye irritation or damage.
4. Pay attention to the source of fire: Unsaturated resins have flammability, avoid approaching open flames or high-temperature objects.
5. Storage precautions: When storing unsaturated resins, avoid direct sunlight and high temperatures, and maintain a dry and ventilated environment.
